Smoke pipes

ABSTRACT

The present disclosure is directed to smoke pipes to draw smoke from a bowl with burning material, through a cooling chamber, and into a mouthpiece. The smoke pipes each include a coupler, a bowl, and a cooling chamber. The coupler removably receives the cooling chamber and the bowl. Material is burned in the bowl and resulting gasses are drawn into the cooling chamber and then into the mouthpiece by applying suction to the mouthpiece. The smoke pipes may include downstems extending into the cooling chamber from the portion of the coupler into which the cooling chamber is removably inserted. The cooling chambers may be capable of holding liquid. The smoke pipes may also include a perforated disc removably placed between the cooling chamber and the coupler so that after the smoke passes through the cooling chamber it then passes through the disc and into the mouthpiece.

This application claims priority to copending U.S. Application Ser. No. 62/178,378, filed on Apr. 9, 2015, which is hereby incorporated by reference for all purposes.

BACKGROUND

The present disclosure relates generally to smoke pipes. In particular, pipes for generating smoke from burning material and drawing it through a cooling chamber and into a mouthpiece by suction are described.

Known smoke pipes are not entirely satisfactory for the range of applications in which they are employed. For example, existing smoke pipes with cooling chambers use bowls removably mounted on a piece that is separate from the mouthpiece and commonly down near the bottom of the cooling chamber with the cooling chamber itself providing a mouthpiece. Thus, the distance between the bowl and the mouthpiece is commonly defined by the size of the cooling chamber. In addition, causing smoke to travel a further distance through a cooling chamber commonly requires creating more distance between the bowl and the mouthpiece and makes the pipe harder to operate. A user may create a long stem from the bowl to the cooling chamber to reduce the user's distance between the bowl and mouthpiece, but this adds complexity and increases the risk of breaking. Further, conventional smoke pipes may use liquids in the cooling chamber and are prone to splashing the liquid on the mouthpiece when suction is applied.

Some existing smoke pipes may attach mouthpieces to lengths of tubing that allow a user to reach the bowl while operating the mouthpiece and create more distance to travel within the cooling chamber, but this adds complexity, makes it more difficult to simultaneously operate the bowl and the mouthpiece while holding the cooling chamber, and makes cleaning more difficult.

Thus, there exists a need for smoke pipes that improve upon and advance the design of known smoke pipes. Examples of new and useful smoke pipes relevant to the needs existing in the field are discussed below.

SUMMARY

The present disclosure is directed to smoke pipes for a user to draw smoke from a bowl with burning material, through a cooling chamber, and into a mouthpiece. The smoke pipes each include a coupler, a bowl, and a cooling chamber. The coupler removably receives the cooling chamber. In another portion outside the cooling chamber, the coupler removably receives a bowl where material can be burned and from which the resulting gasses can be drawn into the cooling chamber and then into the mouthpiece, which is another part of the coupler and outside the cooling chamber, by applying suction to the mouthpiece.

In some examples, the smoke pipes may include downstems extending into the cooling chamber from the portion of the coupler into which the cooling chamber is removably inserted. In some further examples, the cooling chambers may be capable of holding liquid and the smoke pipes may include a perforated disc. The perforated disc is removably placed between the cooling chamber and the coupler so that after the smoke passes through the cooling chamber it then passes through the disc and into the mouthpiece.

DETAILED DESCRIPTION

The disclosed smoke pipes will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.

Throughout the following detailed description, examples of various smoke pipes are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.

The present disclosure relates to smoke pipes for generating smoke from burning material and drawing the smoke through a cooling chamber and into a mouthpiece by suction. The disclosed smoke pipes use a coupler, comprised of a mouthpiece, a portion that receives a cooling chamber, and a portion that receives a bowl for burning material. The coupler provides a simple way to hold the smoke pipe while using it, as well as providing easy clean-up. In some examples, a downstem from the coupler into the cooling chamber provides a way to increase the distance the smoke travels through the cooling chamber without increasing the distance from bowl to mouthpiece or using long bowl or mouthpiece stems. In further examples, the disclosed smoke pipes provide a cooling chamber that can hold liquids and a perforated disc that prevents the liquids from splashing into the bowl or mouthpiece during use.

With reference to FIGS. 1-9, a first example of a smoke pipe, smoke pipe 100, will now be described. The reader will appreciate from the figures and description below that smoke pipe 100 addresses shortcomings of conventional smoke pipes.

As can be seen in FIGS. 1, 4, 6A, 6B, and 6C, coupler 110 includes first receiving portion 112, second receiving portion 114, and mouthpiece 116. First receiving portion 112 removably receives bowl 120. Second receiving portion 114 removably receives cooling chamber 132. In the present example, first receiving portion 112 is located substantially proximate to mouthpiece 116. In this example, first receiving portion 112 is disposed in line with mouthpiece 116 and so that second receiving portion 114 is disposed so as to place the cooling chamber at an angle that suggests or is close to perpendicular to the line, but it should be understood that coupler 110 can be configured in any suitable size or arrangement locating first receiving portion 112 substantially proximate to mouthpiece 116 that the user desires according to the user's particular needs and desires. In the present example, coupler 110 also provides a handle for smoke pipe 100.

Coupler 110 avoids the need for a long stem to bring a bowl and mouthpiece close to each other for the user to see and reach both. Its arrangement also reduces neck strain associated with conventional smoke pipes that open at the top of the cooling chamber. It also prevents the need for long tubing, thus making it much easier tor a single person to use the pipe while holding it or to move it.

It should be understood that coupler 110 is made from a heat-resistant plastic sufficient to withstand the temperatures ordinarily associated with using a lighter to burn material for smoking and resist imparting any scents, flavors, or other contaminants to the gasses drawn from the burning material. Coupler 110 can be made from any other suitable material according to the user's particular desires and wishes such as, for example brass, stainless steel, dense-grained wood, corn cob, clay, glass, or ceramic.

As shown in FIGS. 3, 6A, 6B, and 6C, first receiving portion 112 is a substantially cylindrical void defined by coupler 110 that extends partially into coupler 110. A tube with a more narrow diameter than first receiving portion 112, first coupler tube 113, extends through coupler 110 from first receiving portion 112 into second receiving portion 114. Smoke drawn from burning material in bowl 120 passes through first coupler tube 113 and into second receiving portion 114 without first intermingling with mouthpiece 116.

FIGS. 5A, 5B, and 5C illustrate bowl 120. Bowl 120 is removably inserted into first receiving portion 112 as shown in FIG. 1. Bowl 120 is substantially cylindrical and shaped so it sits in the first receiving portion. In the present example, bowl 120 is a cylinder and made of titanium, but any suitable shape and material can be used, according to the user's particular needs and wishes. For example, the bowl may be made of any material capable of holding a burning material such as, for example, brass, stainless steel, dense-grained wood, corn cob, clay, glass, ceramic, or any other suitable material. Further, the bowl might have a square- or hexagonal-shaped cross section, or might be a mesh screen sized to sit over the first receiving portion.

As can be seen in FIGS. 3, 6A, 6C, and 9, second receiving portion 114 is a substantially cylindrical void defined by coupler 110 and shaped to removably accept cooling chamber 132. Smoke drawn from bowl 120 passes into the cooling chamber through second receiving portion 114. The second receiving portion removably accepts the cooling chamber using screw-in threads in the present example, but any means of removably inserting the cooling chamber can be used.

FIGS. 2, 5A, 5B, and 5C illustrate the present example in which the bowl includes base 121, base portion 122, bowl portion 124, flange 126, holes 128, and side holes 129. Base 121 is narrower at its base, where it inserts removably into first receiving portion 112, and wider at its top where it includes flange 126. Flange 126 extends radially from bowl portion 124 to a diameter that is wider than first receiving portion 112 so that the base portion sits removably in the first receiving portion. In this way, the bowl is held removably in place by force of gravity and can be lifted off by the user during operation. Further, flange 126 includes ribbed sides that increase the surface area of bowl 120 to disperse heat away more quickly than smooth sides and provide the user a more secure grip.

As shown in FIGS. 4, 5B, and 5C, bowl portion 124 is a circular depression in the center of flange 126 that does not extend all the way through base 121. Base portion 122 is an opening defined by base 121 opposite from bowl portion 124. Base 121 defines one or more holes 128, which are voids extending through base 121 placing bowl portion 124 in fluid communication with base portion 122. In the present example bowl 120 includes seven holes 128, but other examples may include more or fewer holes. Users place the material they want to burn for generating smoke into bowl portion 124 where it is held such that users can apply a flame to it, typically with a lighter. Smoke or other gasses from burning material can be drawn into second receiving portion 114 through first coupler tube 113 as shown in FIG. 2.

As can be seen in FIGS. 4, 5B, and 5C, base 121 defines side holes 129. Side holes 129 are voids extending from base portion 122 through base 121 at an approximately 90° angle relative to holes 128. In the present example, bowl 120 includes two side holes 129, but other examples may include more or fewer holes according to the user's needs and desires. Side holes 129 allow fresh air to flow into the cooling chamber when bowl 120 is lifted far enough out of first receiving portion 112 to expose side holes 129. While smoke pipe 100 may be used without side holes 129 because the tapered shape of base 121 allows air to flow past its sides when it is lifted, side holes 129 increase the available space for air to flow by allowing air to also flow into and through base portion 122.

Bowl 120 is made of titanium, which resists imparting any scents, flavors, or other contaminants to the gasses drawn from the burning material, but any suitable material can be used such as, for example, brass, stainless steel, dense-grained wood, corn cob, clay, ceramic, or any other suitable material. Further, bowl 120 is generally cylindrical in the present example, but can be any shape the user desires such as, for example, a square- or hexagonal-shaped cross-section. In addition, bowl 120 is held removably in place by force of gravity in the present example, but any suitable means of holding bowl 120 can be used.

As can be seen in FIGS. 2, 3, and 4, disc 130 is a substantially circular disc with an opening in its center sized to allow gasses to pass from bowl 120 to first coupler tube 113. Disc 130 is magnetized to removably hold bowl 120 with more security than gravity alone, such that the user may still remove bowl 120 with one hand during use. Disc 130 works with a bowl that is attracted to disc 130, but its use with any bowl does not limit the operation of the smoke pipe. Disc 130 in the present example is removably secured at the bottom of first receiving portion 112 by tension of the narrowing side walls of first receiving portion 112, but it could be held by any suitable method, including with metal in coupler 110, with an adhesive, or by molding it in place.

Unlike conventional bowls, the shape of bowl 120 enables it to stand upright on its own when removed from coupler 110. In this way, bowl 120 reduces the likelihood of material falling out when the bowl is removed from the pipe and when the user sets it down. Flange 126 further reduces the likelihood of bowl portion 124 from reaching an angle sufficient to allow material to fall out when bowl 120 is set clown upright or on its side.

As can be seen in FIGS. 1, 3, and 4, cooling chamber 132 is removably inserted into second receiving portion 114, in this case using screw-type threads although any suitable means of removably securing the cooling chamber may be used. Cooling chamber 132 is a cylinder, in this case wider at its base than at its top to provide stability when standing upright with the other components of smoke pipe 100. In this case, cooling chamber 132 is made of a glass that can hold ice or liquids, including water, and withstand the heat from gasses drawn in from the bowl, cold temperatures such as ice, and the temperature changes that occur when such hot gasses interact with cold ice or liquids in the cooling chamber. It should be understood that cooling chamber 132 may be made from any suitable material such as, for example, brass, stainless steel, dense-grained wood, clay, or ceramic, according to the user's particular needs and desires.

FIGS. 1, 2, 3, 8, and 9 illustrate downstem 134 in use with smoke pipe 100. Downstem 134 includes first end 136, entry tube 137, second end 138, exit tubes 139, and percolation cap 140. Smoke pipe 100 may be used without a downstem, so that gasses drawn in from bowl 120 enter cooling chamber 132 at second receiving portion 114. When smoke pipe 100 is used with downstem 134, the downstem is in fluid communication with bowl 120 so that gasses drawn from the bowl are routed through the downstem.

In the example shown in FIGS. 2, 4, 6A, and 9, downstem 134 is an elongate tube, in this case made of plastic though any suitable material that withstands the temperatures of smoke pipe 100 during can be used, that removably inserts into second receiving portion 114 with screw-type threads at first end 136, though any suitable means of removably securing it may be used. Further, first end 136 inserts into the second receiving portion before the cooling chamber is inserted. Downstem 134 contains a hollow tube defining entry tube 137. Entry tube 137 communicates with first coupler tube 113 so that gasses drawn from bowl 120 pass into entry tube 137. Gasses exit from entry tube 137 at second end 138, which is located distal from first end 136.

As shown in FIGS. 1, 3, and 8, downstem 134 includes percolation cap 140 located at second end 138. Percolation cap 140 is a hollow metal piece defining holes. The cap removably attaches to second end 138. Gasses exit from entry tube 137 through percolation cap 140 both through side holes and through the bottom, more effectively spreading the gasses into cooling chamber 132. When there is a liquid, this produces more bubbles so that more surface area is in contact with the liquid. When there is a solid like ice in the cooling chamber, this creates more interaction between the gasses and the solid, enhancing the filtering and cooling or warming effect of the user's chosen liquid or ice. The cap can be removed for cleaning. It should be understood that smoke pipe 100 may be used without percolation cap 140, but that when the percolation cap is used the gasses exiting from entry tube 137 must then pass through percolation cap 140.

As illustrated in FIGS. 2, 4, 8, and 9, gasses in the cooling chamber are drawn out by applying suction to mouthpiece 116. This suction draws the gasses through exit tubes 139. Exit tubes 139 are voids defined by first end 136 and positioned so they surround the outside of entry tube 137.

Smoke pipe 100 includes perforated disc 142 as shown in FIGS. 2, 3, and 4. In this example, perforated disc 142 is a roughly fiat, round metal disc with a hollow tube in the center defining a hole through the center of the disc, center tube 144, and additional holes surrounding center hole 144 that also go through the disc, secondary holes 146. While smoke pipe 100 can be used without perforated disc 142, in this example perforated disc 142 is removably inserted into second receiving portion 114 first, before either downstem 134 or cooling chamber 132. Downstem 134, when used, or cooling chamber 132 hold perforated disc 142 in place by squeezing it when the downstem or cooling chamber is inserted.

As shown in FIGS. 2 and 4, center tube 144 extends into first coupler tube 113 and into entry tube 137, forming an air-tight path for gasses to travel from the bowl into entry tube 137. Secondary holes 146 sit over exit tubes 139, forming a path for gasses to travel from the cooling chamber into mouthpiece 116.

As can be seen in FIGS. 2 and 4, the shape of exit tubes 139 are more narrow in diameter than second receiving portion 114 and cooling chamber 132. This reduces the likelihood of water or other liquids in the cooling chamber from splashing up into the mouthpiece during use. The shape of mouthpiece 116, which bends as shown in FIG. 6b and is narrower where it opens into second receiving portion 114, also reduces the likelihood of water or other liquids splashing into it from the cooling chamber. Perforated disc 142 reduces, or preferably prevents, water or other liquids from splashing up into the mouthpiece. It should be understood that smoke pipe 100 may be used without downstem 134 or perforated disc 142, or it may be used with either one alone or with both.

FIGS. 4, 6A, 6B, 6C, 7, and 8 illustrate mouthpiece 116. Mouthpiece 116 is a void defined as a tube through coupler 110 and opening through second receiving portion 114. Mouthpiece 116 does not connect to first coupler tube 113. Gasses drawn from bowl 120 into cooling chamber 132 are then drawn through mouthpiece 116 by applying suction to mouthpiece 116, usually created with the user's mouth as shown in FIG. 8 while lifting bowl 120 from first receiving portion 112. As shown in FIG. 7, mouthpiece 116 is a round tube, sized large enough to hold an ordinary lighter. It should be understood that the mouthpiece can be any suitable shape and size, according to the user's particular needs and desires. The length of mouthpiece 116 places the user's mouth a safe distance from bowl 120 to avoid burns from using a lighter or from the burning material, while coupler 110 enables an individual to carry and to use smoke pipe 100 while holding it alone as shown in FIG. 8 even when the cooling chamber is filled with water.

FIG. 3 illustrates how the components of smoke pipe 100 may be taken apart for easy cleaning, storage, or transport. The components of conventional smoke pipes are often fused together or positioned in such a way that hand-cleaning is more difficult than with smoke pipe 100. That the components may be separated and cleaned, or replaced individually, makes smoke pipe 100 more sanitary, safer, and cost-effective than conventional smoke pipes. Removing cooling chamber 132 separately also makes it easier to empty or fill with new liquid or ice.

Turning attention to FIG. 10, a second example of a smoke pipe, smoke pipe 200, will now be described. Smoke pipe 200 includes many similar or identical features to smoke pipe 100. Thus, for the sake of brevity, each feature of smoke pipe 200 will not be redundantly explained. Rather, key distinctions between smoke pipe 200 and smoke pipe 100 will be described in detail and the reader should reference the discussion above for features substantially similar between the two smoke pipes.

As can be seen in FIG. 10, smoke pipe 200 includes coupler 210, bowl 220, cooling chamber 232, downstem 234, and perforated disc 242. Smoke pipe 200 differs from smoke pipe 100 in that coupler 210 is shaped differently from coupler 110.

FIG. 10 illustrates coupler 210 in which first receiving portion 212 and mouthpiece 216 are disposed in line with each other so that second receiving portion 214 is between the line formed by the mouthpiece and first receiving portion. In the present example, second receiving portion 214 is disposed in a way that is close to or including perpendicular to the line, but it should be understood that second receiving portion 214 may be disposed at any suitable angle the user desires. It should be further understood that while the present example illustrates a roughly T-shaped coupler, coupler 210 may dispose first receiving portion 212, mouthpiece 216, and second receiving portion 214 in any configuration the user desires that places the mouthpiece and first receiving portion in line with each other. Coupler 210 can also serve as a handle for the user and enable one person to use the smoke pipe while holding it, but it should be understood that the coupler can form any shape or size the user desires.
